Subject: [PATCH] media: lnbh25: use %*ph for I2C write dump

Replace the hand-rolled %02x formatting of the I2C write buffer in the
lnbh25 driver with the %*ph format specifier. %*ph is the preferred
helper for printing a buffer in hexadecimal and makes the debug output
clearer and more consistent.
